DESCRIPTION

The M74HC670 is an high speed CMOS 4-

WORD x 4 BIT REGISTER FILE (3 STATE)

fabricated with silicon gate C2MOS technology.

The M74HC670 is 4 x 4 Register File organized as

four words by four bits. Separate read and write

inputs, both address and enable, allow

simultaneous read and write operation. The

3-state outputs make it possible to connect up to

128 outputs to increase the word capacity up to

512 words. Any number of these devices can be

operated in parallel to generate an n-bit length.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
